About this app

Octopus Watch is the easiest tool to manage the (smart) tariffs provided by Octopus Energy in the UK. Octopus Watch is a paymium app for Android offering both a standard version as a one-time purchase, and an optional subscription with additional features.

Ready to supercharge your savings?

Save significantly on your electricity bill, regardless of whether you're on Agile, Go, Cosy, Flux, Tracker, or any fixed tariffs (basic or eco 7). Thinking of joining Agile? Log into the app with just your postcode and check out local rates. If you want to see your consumption history, you'll need an Octopus Energy account and an active smart meter. Please note that support for Intelligent and Intelligent Go is currently limited, with only default off-peak times available. For the latest status on tariff support check out the wiki: https://wiki.smarthound.uk/octopus-watch/tariffs/ .

With the standard version of Octopus Watch, you'll have all the tools at your fingertips to effectively manage your tariff:
• View your current rates in an instant (including for gas trackers).
• See all your upcoming rates in an easy chart and table.
• Instantly get the cheapest times to run appliances or charge your EV, and save big!

• Receive alerts when the next day's Agile rates are available.
• See your historic day-by-day usage.
• Use the new micro metrics to quickly see trends in your usage.
• See when your meter fails and how much data is missing.
• Understand how weather influences your usage.
• One tap comparison to see how your tariff compares to Agile, Go, and SVT.

Works well, crams a lot into the interface, but for some reason it's used over 1Gb of mobile data on my phone this month! I'm now concerned it's doing something "untoward" as well as the job it's meant to do. Surely the small daily data downloads can't amount to that much? UPDATE: feedback appreciated from the developer. I'm going to tweak some settings.

Hi Iain, the cause is missing data and how the API works. The API does not notify the app of missing data. What the app resorts to is polling a.k.a. ask it every now and then. This can indeed cause a lot of data usage, even with all the workarounds. You can accept missing data or you can limit data to 3 months in Options. Both greatly reduce usage.

Brilliant app. Had it for a couple of years now. Having this information to hand is a life saver. Definitely worth the cost for subscription. I would love to know if there would be an android/wearOS app available... To have this on my pixel 3 watch would be even better (especially when you have put your phone on charge, then remember to set the dishwasher up and realise you left the phone behind! Fitbit loves it😂)

Absolutely cracking app and well worth the money for the full subscription. The details, reports and forecast are excellent and the data is really clear. The only thing I'd suggest is to make it easier for people to realise that if you hold down the kWh etc, you can change it to £ and vice versa. I only discovered it by accident. Overall though, brilliant.
